' It: has heretofore been theusualpractice to'connect bandjends by theuse of.rivets,'but when it is desired to separate or loosen the ends,the rivetsar'e destroyed and the band ends aredamaged' but with thepresent device a separable connecter may be disengaged from the bandends without injury thereto and re-used, Inthe'present invention, bandends areprovided with registering slots that have rounded ends and thewire frame that comprises looped portions to be extended through the'registering slots is constructed of strong tempered steel to reduceshearing action on the connecter device resulting. in

the band ends beingconnected together in a separationthereof.

In the form of the.inven tion illustrated in Figures 1 to 5,theconnecter device includes a Wire frame of rectangular formation bent 2with the section thereof oppositethe side 2 formed of the ends 3 ofthewire strand as illustrated in Figure 4," providing as'ubstan V tiallyflatlbase portion for. fiat'contact with so r be presently described.The opposite sides a joint formed by overlapping band ends to l'of thewire frame, are each provided with an ofisetperpendicular loop portione'pro ectin'g from one side of the wire framefand out ofthe plane of thebase portion. The

moreefiicient manner and permitting easy.

overlapping band ends 5 are each provided with a pair of spaced slotswith the respective slots of the'band ends registering when the bandends are in overlapped relation, the Wire frame illustrated in Figure 4being engaged with the outer face of one band end with the loop portions4L thereof projecting through theregistering'slots as shown in Figures-1to 3.

The loop portions -of the wire frame project outwardly of the outer bandends as illustrated in Figures 2 and 3 and a retainer ;.key as shown inFigure 5 is engaged with the projecting portions of the loops in aninterlocking manner for connecting the two parts of the device togetherand for securing the overlapping bandends in assembled relation. Theretainer key is formed of a single strand of wire bent into U-shape toprovid'eside legs 7, each leg having an opposed inwardly directednotched portion 8 adjacent the closed end of the key while an inwardlydirected angular shoulder 9 at the outer end of eachside leg 7'of thekey provides adj'acently positioned terminal sections 10. The closedend. ll'of the key is perpendicularly offset to provide a finger grip ina plane laterally of the overlapped ends of the band. To engage theretainer key with the loop portions 4: of the wire frame the terminalends 10 of thekey are moved toward each other for passage through theprojecting portions' of they loops 4 to position the notched portions 8'in engagement with the first loop and the shoulders 9 in engagement withthe second loop as illustrated in Figure 1, the re tainer key being of aresilient character for maintaining the position shown in Figurelrelativ'eto the wirefranie for retaining the overlapping band'ends inassembled relation. jThe keyis disengaged fromthe wire frame movingtheterminal ends 10 of the side legs of'the key toward each other and atwhichtimethe fkeymay be readily withdrawn fromthe loop portions 4 of thewire frame, the latter then disengaged from the registeringslots 6 inthe band ends and the bands separated. j

Another form of retainer key is illustrated in Fi ure 6 and is of thegeneral character shown in Figurefi, comprising side legs 7a with angleshoulders 9a adjacent the terminal ends 10a,.angle shoulders 80; beingprovided adjacenttheclosed end of the key with the wire section formingthe closed end bent into a'circular loop 12. The shoulders SaVand 9a ofthe key shown in Figure 6 are engageable with the loop portions 4'bf thewire frame.

Another form of retainer key is illustrated inFi'gures 7 to 13, the wireframe illustrated in detail in Figure 7 being the'same as that shownin'Fignre e and designated by simi lar reference characters. ,The bandendse are llustratedin F gure 7, in spaced relation. i

to more clearly illustratethe spaced slots6 naemm that have curved orrounded end-wallsf6a. The retainer key as illustrated insaid figuresembodies side leg portions 13 arranged in closer relationship than theside leg portions 7 of the retainer key asillustrated in Figure 5, theouter end of the key being angularly bent in each leg thereof in anoutward 'direction to provide substantially V -portions definingshoulders 14 and 14a with the terminal ends 15 of the -V-sl1apedportions of the legs overlapping in normal vposition as illustrated inFigures 7, 8 and 10', the side leg portions 13 being normally disposedin parallel relation as illustrated. The closed end of the retainer keyat the innerends of the side leg portions 13 are angularly bent in anoutward direction to provide shoulders 16 terminating in parallelportions 17 and a perpendicularly ofiset finger-griplS forming thecross-bar of the closed end of the retainer key. In assembling'the bandends illustrated in Figures'Z-to 13, the respective slot-ted openings 6are alined and the loops 4 upon the side portion 1 of the wire frame areextended through the registering openings 6 to project laterally of'theoverlapping band ends as illustrated in Figures Sand 9. The shoulderedends 14 and 14a are then moved toward each other-for passage'through thefirst loop 4 and they are similarly compressed for passing through thesecond loop to assume the position shown in Figures with the shoulders'14 and 16, engaged with the loops 4 of the wire frameas illustrated.The

adjacently positioned side leg sections-13V of the retainer key aredisposed between the two loops 4 and the retainer key is maintained 1nengagement with the-loops '4 by the angle shoulders 14 and '16. v i 7 rIn the form of invention illustrated in Fig ures 14 to 16, the retainerkeyzis similar to the form of key illustrated in Figures 7 to- 13 exceptthat the side leg sections 13 thereof are of reduced length while theoverlapping band ends are provided witlrsingle ireg1stering slottedopenings for the reception of a single loop member carried by a wireframe.

The wire frame carrying the, singleloop is formed of a single strand ofwire having op posit-e ends thereof bent into arcuate formation as at19, disposed in the sameplane and combining to form a substantiallycircular frame with the intermediate portion of the wire, strandextending transversely ofrthe arcuate end portions as at :20 with'aperpeiv dicularly extending loop 21' arranged inter-1 mediate the endsthereof. The band endsfia are each provided with asingleslotted opening5?) that when mated receive the loop:,19 of the wire frame whichprojectsrfroinfione side of the mating bandends thekev illustrated inFigure 14 as previously stated be-' .ingof similar construction tothekey shown in Figures 7 to 13 except that :the sid'eleg" portions 13aare of reduced length to br'i'ng the shoulders and 16 into closerrelation: shipfor cooperation withsthe single loop 21.' V p =Acombined-wire frame carrying loop and retainerkey is illus'tr'ated-inFigures'17 to 20. The' ico'mbined loop-carrying'frame and retainer keyas illustrated in Figure 17 is a formed of a. single strand of wirebentsintermediate its endsto provide across bar 22 and parallel sidelegs23 thatxcarryperpendicular oifsetloops 24 intermediate their ends.The

side legs 23 are reversely bent'as at 25 to overlie andbe spaced fromthe side leg portions 23 with the terminal ends of the reversely bentportions 25 bent outwardly to provide c retainer keys'26l.,The band ends5 are ofthe' and being provided vwith pairs "of: spaced slotted openings6'l1aving rounded ends 6a: Thebandends 5 are assembled as illustrated inFigure 18 with the "loopportions24' projected through the registeringopenings 6 -w'ith theleg sections 25 overlying the oppo site side orface of the bandendfl Theleg sections 25 arethen moved toward each otheras shown in Figure 19 toposition the key ends same constructionasillustrated in Figures 1 25 therein aline'ment with the loops 24 andwhen pressure on the legends 25' is relieved;

the key ends 26 thenmoveinto the projecting portions of the loops 24asshown in Figure 20.

Another form fof -loop frame and. retainer key are illustrated inFigures 21 to 28 wherein double" loops are provided, "but the "re 1tainer key is interloc'kingl y engaged with only one loo-p',' theloopcarrying wire frame as illustrated in Figure 21 being of U-shape Themanner of attaching the retaine'rkey to the looped portions of' the wireframe is illusiio trated in Figures 23to27 the. spaced ends of V theside legs 30' being' movedtoward 'each other for insertion through thefirst loop 29, pressure upon the closed end ofthe key causing the legs30 to" move into crossed relation as shown in Figures241and 25} forpassage through-the second l oop and to position the i sockets33"'ofthe' notches'32 in position for enclosing opposite sides of thefirst loop 2941s shown in Figure 26 the key being 'securely retained inposit on'even though the-free ends of the legs should be jnioved intoabut ting engagement :as illustrated in- Figure .27 -The closed'endof-theretainei key'is upset as illustrated in"Figure'28*tofacilitate apf plic'a'tion and removal thereof in. association with .theloops 29 of the wire-frame member.

From the above detailed description of the invention, it is believedthatthe several forms of construction and methods of operation will atonce be apparent,it being noted that ineach form of the invention, awire member-is disposed perpendicularly to the ends of thebands, the.wire member embodying either a single or double loop projectedthroughregistering slotted openings in the band ends with a retainer keyassociated with the projecting'ends of the loops'at one side of the bandends. Also, by the provision of round wire that may be highly temperedand roundingof. the ends of the slots in the band ends, thereis a strongtendency to prevent any shearing action or tearing of the band iron atthe slotted portions and upon removal of the retainer key anddisplacement of the .loop portions from the band end slots, the bandends are readily separated without damage thereto. 7 c 7 Ylvhile-flthereare herein shown and described the preferred embodimentsof the present invention, it is nevertheless to be understood that minorchanges may be made therein without departing from the spirit and scopeof the invention ,asclaimed.
